Answer:
Step-by-step explanation:
Te processing fee was applied to the discounted price.
The discounted price is
- 78 - 40% =
- 78*(100 - 40)/100 =
- 78*0.6 =
- 46.8
Amount of fee is
- 20% of 46.8 =
- 0.2*46.8 =
- 9.36
The formula for density is:
Mass/Volume, or in other terms, mass divided by volume.
So, lets look at our numbers:
We know our mass is 84 grams, and our volume is 12 cc. So, all we need to do is divide 84 by 12, which is 7.
So, the density is 7.
If you have 6 pounds of sunflower seeds and make 0.75 packages, 6/0.75 is 8 so you can make eight .75 packages with 6 pounds
Answer:
The 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is (0.472,0.766).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
In a sample of 42 water specimens taken from a construction site, 26 contained detectable levels of lead.
This means that 
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is (0.472,0.766).
